The plan or system of plans selected is displayed in the instructions window along with additional instructions. If you specified Form 2 plans, the matching Form 1 plans are also displayed. These matching plans are not from the standard but are instead calculated as is also done in the Variables Single For Defective Units dialog box. The Form 1 plans are easier to use. You can print out or copy these instructions to the clipboard by clicking the menu button at the bottom. This the same as right mouse clicking over the instructions window. A popup menu appears with five menu items. The first three menu items resize the instructions in the instruction window for better viewing. The Clipboard menu item copies the instructions to the clipboard in text format. You can then go to your word processor and use the Paste menu item from the Edit menu to insert this text into your document.
When done, click the OK button or press the Enter key to save the sampling plan and close the dialog box. Clicking the Cancel button or pressing the Esc key cancels the changes to an existing sampling plan or the creation of a new sampling plan.
For a new plan, this dialog box is displayed by selecting the characteristic Defective Units and the type ANSI Z1.4 Sampling Plan from the Enter New Sampling Plan dialog box. To edit a plan, double click on it in the List Sampling Plans window.
